1 GENERAL SAFETY INFORMATION
1.1 Scope of the document
These instructions are applicable only to the explosion-protection version of the TDR level
transmitter. For all other data, use the Quick Start and Handbook. If you do not have these
documents, please contact the nearest office or download them from the manufacturer's
internet site.
INFORMATION!
The information in these supplementary instructions only contains the data applicable to
explosion protection. The technical data for the non-Ex version in the Handbook shall be valid in
its current version, provided that it is not rendered invalid or replaced by these supplementary
instructions.
WARNING!
Installation, commissioning and maintenance may only be carried out by "Personnel trained in
explosion protection".
1.2 Device description
OPTIFLEX 1300 C
This device is a 2-wire level transmitter that uses TDR (Time Domain Reflectometry) / Guided
Radar technology. If the device has the FOUNDATION™ Fieldbus or the PROFIBUS PA output
options, it is connected to the fieldbus network as a 4-wire device. The device measures the
level, distance, volume and mass of liquids, liquid gases, pastes, powders, slurries and granular
products. It is also suitable for the continuous and simultaneous measurement of level and
interface of 2 liquids. Measurements are displayed via a DTM (device type manager) for remote
communication or an optional integrated display screen with wizard-driven setup and online
help functions.
The level transmitter is approved for use in potentially explosive atmospheres when equipped
with the appropriate options.
1.3 Standards and approvals
DANGER!
In compliance with European Directive 94/9/EC (ATEX 100a), the ATEX version of the device
described in these Supplementary Instructions conforms to European Standards EN 600790:2006, EN 60079-1:2007, EN 60079-11:2007, EN 60079-15:2005, EN 60079-26:2007, EN 6007927:2008, EN 61241-0:2006, EN 61241-1:2004 and EN 61241-11:2006. The Ex ia / Ex iaD and
Ex d[ia] / Ex tD[iaD] versions are certified for use in hazardous areas by the KEMA Quality B.V.
under KEMA 04ATEX1219 X. The Ex nA version is certified for use in zone 2 under our sole
responsibility. For more data, refer to the manufacturer's declaration given on the CD-ROM
supplied with the device. You can also download the manufacturer's declaration from our
internet site.
WARNING!
Carefully read the ATEX approval certificate. Obey the boundary conditions.
The certificate is given on the CD-ROM supplied with the device. You can also download the
certificate from our internet site.
